I was using Waze on a road trip last week. I noticed at one point that the mileage wasn't correct to my destination (it's a route I frequent so I know times and mileage for it). I just assumed that Waze had picked a bad route, then I noticed the ETA was still correct for my normal route.

This shows that I should cover 83 miles in 60 minutes (not likely on these highways). Right after I took that screenshot, I made a turn on route and the mileage dropped to 55 miles (correct) with the same ETA.

I have notice this issue as well when selecting a route. I think the initial calculation is "as a crow flies" but then when I actually start on the route it will auto-correct. So what was said to be a 23 mile route is actually 30 for example. Also, I've noticed that sometimes the miles remaining doesn't update. I will be just a couple of miles from my destination but Waze says I still have 16 miles remaining. This a recent quirk but the other route calculation error has been on-going.
